As in, channels where the presenter is laid back, calming, and the content is slower paced and chill. My go two examples are LGR for retro computer stuff, and Hainbach for experimental tape music.
Click spring for watchmaking. It can take 6 months to do a single build and they’re insanely intricate.
Paul Harrell (RIP) for guns. His presentation style was a masterclass on how to convey information in a unbiased manner. Anyone who teaches anything to anyone should take notes.
He was entertaining without trying to be entertaining. If that makes sense? The man was demonstrating and testing hypotheses without giving two shits about likes and subscribes. Loved his dry humor, sometimes caught me off guard. “Wait! Did he really just say that?!”
Not Youtube, but on my streaming service there’s an America’s Test Kitchen channel and a “The Repair Shop” channel.

“Tally Ho” comes to mind, where a guy turns a famous wreck into a boat.
bigclivedotcom - I have no idea what he’s talking about 90% of the time but he’s generally a relaxing watch.
Ali Spagnola and Aging Wheels aren’t quite what you’re describing in terms of being calm and chill but I still love their stuff.
Seconding others’ recommendations for Technology Connections, TheCrafsMan, Cathode Ray Dude, and Techmoan.
Florian Gadsby has an amazing channel for pottery. I find it incredibly relaxing and he is an amazing potter.
Bill Hammack - TheEngineeringGuy
All manner of engineering gadgets and phenomena explained clearly and calmly.

I saw a lot of channels that sprung to mind already posted. But I want to strongly recommend Thomas Shahan for super chill bug photography and mellow voice overs. Worth checking out even if you’re not into macro photography.
Attoparsec, Chronova Engineering, and polymatt all fit that description.
Baumgartner Restoration. I watch it like bedtime stories.
Joe Pera: https://m.youtube.com/@JoePeraComedy In theory comedy, but the most wholesome relaxing kind you can imagine.
WAY OUT WEST with Sandra and Tim, Kind of a farm / homestead in Western Ireland. https://m.youtube.com/@WayOutWestx2
Ogmios - dude drives carefully around London, is nice to pedestrians and other traffic, and has a calming voice.
Ishitani Furniture (no talking, plus an occasional pet): https://m.youtube.com/channel/UC7FkqjV8SU5I8FCHXQSQe9Q
He does great work!
Andrea Borman’s linux channel.
I only just found them last night but manofdutch scratches that kind of itch for me with Minecraft builds
